Yeah, my coach from back home was talking about that Qi running book one time.
I wasn't really focused on this aspect of training at that point so it went over my head a little, but from what I gathered it was again relative to position, movement, balance etc while running - for greater productivity and efficiency.

I'm a bit of a youtube addict at the moment, been neglecting the books pretty much entirely lately.

As regards, just what I think, on words influencing the subconscious.
I think that's spot on. I didn't really think of or understand it that way, but obviously that's what's happening.
It's funny, the various combination of words, or perhaps the understanding that a particular individual takes out of them, that's where they become effective - like the magic words for that person :) - for me at least.

Just coming up with them words "focus on movement, focus on movement", that's what I'm repeating to myself during training, and it seems to working - perhaps the word "movement" triggers something in the brain which compares your current movement to movement one has seen or learned at some stage, and adjusts the current state accordingly.

Another way to put it maybe: focusing mentally on how you wish the situation to manifest itself as such, knowing the area you must focus on in order for this to be the case - triggering that by using certain words - talking to our subconscious, as you say - and thus productivity is most forthcoming.

I know for myself, just from watching some fighters on youtube - Melvin manhoef, paul daley, duance ludwig etc. just seeing them, seeing how effective their movement is, visualizing it, comparing it to what I'm doing and using that to develop personally, that's what seems to work for me.

I guess it's just the key words "focus on movement", however that works in the brain, it just causes this type of activity I guess.

Another way to look at it maybe is, telling ourselves that, allows us to come out of our subconscious a bit more - become more conscious of our movement as such?
Wild speculation there really, but funnily, in an interview with Mike Tyson (done by Larry King I think), he commented on the importance of this in his training - consciousness.
He was very conscious of his speed - stemming from his movement.

At a later time, after he was released from prison, he said he increased his consciousness as regards his behavior as such; not just acting wildly out of instinct, but premeditating situations and being more thoughtful and conscious.
Perhaps this is the same thing that applies to movement during training.

I wish I had the patience to sit down and read a few books on the subject or something, understand the whole mechanics of the brain, conscious, subconscious etc. a bit better..
but so far so good anyway.
